WINDOW CONSTRUCTION.

SPECIFICATION forming part of Letters Patent No. 784,707, dated March 14, 1905.

Application filed February 9, 1903. Serial No. 142,457.

To all whom it nuty concern.-

Be it known that I, EDWARD T. ROBINSON, a citizen of the United States, and a resident of the city of St. Louis and State of Missouri, have invented certain new and useful Improvements in Window Constructions, of which the following is a specification.

My invention relates to window constructions, particularly to street-car windows, and has for its object the provision of means whereby the upper and lower sashes may be moved up and down and also may be removed from the window-frame independently of each other, also to attain certain other advantages hereinafter disclosed.

My invention consists in the construction and arrangement of parts hereinafter described and claimed.

In the accompanying drawings, wherein like symbols refer to like parts wherever they occur, Figure l is a front view of a car-window equipped with my invention. Fig. 2 is a cross-section thereof on the line 2 2 of Fig. 1. Fig. 3 is a cross-section of the post and portions of the window-sashes on opposite Fig. 4 is a vertical section on line 4 4 of Fig. 3, showing the pintle on the side of the upper sash in its proper position when the sashes are closed. Fig. 5 is a view in elevation of the window-sash, showingthe bevel on the sash-stile. Fig. 6 is a cross-section of the post on line 6 6 of Fig. 2.

In the present construction the windowopening is formed by an upper framework 7,

In the lower framework 8 is formed a sashreceiving pocket 8, which receives both the upper and lower sashes when lowered there into. The posts are provided with means for holding the upper and lower sashes in their closed position, as indicated in Fig. 2, and with means for permitting the sashes to be lowered and raised and to be removed from the window-frame. The post 9 is made from a single piece of material and is of a construction more particularly shown in Fig. 6. On the inner side of the post a molding 10 is secured, which overlaps a reduced portion 11 of the post to which it is secured. Adjacent tongue 12, which with the overlapping portion 10 on the molding forms a groove 13, which is intended to be used to receive the edges of a curtain or blind Adjacent to the tongue 12 there is formed a sash-groove 14, which receives a suitable projection, as a pintle or pin 15, on the upper-sash frame. Said pintle or pin is preferably a small casting secured to the frame by a screw but it is obvious that this projection may be secured in a number of ways. This groove 14 runs parallel with the curtain-groove 13 and extends from the sash-receiving pocket to the upper portion of the post. At the upper portion of the post this groove is curved rearwardly and downwardly, terminating in a seat 16, in which a pintle 15 rests when the upper sash is in its normal or closed position. About the point where the sash-groove 14 begins to make its rearward bend a passageway 17 is formed, which communicates with said groove 14. This passage-way or slot is formed in but one of the poststhat is, only in one of the posts which form a single window-opening.

Adjacent to the upper-sash groove 14 there is formed on the post a tongue 18, constituting a parting-strip, which terminates considerably short of the upper end of the post, as shown clearly in Figs. 1 and 2. This tongue 18 is preferably integral with the post; but it may be a separate piece. Between this tongue and the outer portion of the post there is formed a groove 19, which receives the lower sash. The outward movement of the lower sash is limited by an inclined shoulder 20, forming the outer wall of the groove, and the outward movement of the upper sash is limited by the usual shoulder 21 and grooved rest 22. The upper portion of the parting-strip 18 is beveled toward the upper end, as shown in Fig. 1 ,:the length of the bevel being proportioned to the length of the lower sash, so as to permit the removal of the same, as hereinafter described. The point of beginning said bevel is indicated on Fig. 2 of the drawings by 18. Also the lower portion of the lower sash is beveled, as shown at 18", Fig. 5. The purpose of beveling these parts is to permit the removal of the lower sash, as will be hereinafter described. To the stile on the lower sash is secured a spring 31,which bears against the parting-strip 18, which is for the purpose of holding the sash firmly in place and preventing rattling of the same and for forming a friction-brake to prevent too quick a downward movement of the sash when it is lowered into the sash-receiving pocket.

Hinged to the inner side of the upper lining of the sash-receiving pocket 8 is a cover 23, the outer edge of which is rabbeted, as shown at 24. The outer lining 25 of said. sash-receiving pocket is beveled, as indicated at 26. The outer edge of the cover 23 projects beyond the inner edge of the lining 25 and over the beveled portion 26. On the lower rail of the lower sash there is formed a shoulder which snugly fits the rabbeted portion of the cover 23. By this construction a close-fitting cover is formed for the sashreceiving pocket, thcrcbypresenting a neat appearance and also serving to prevent passengers from throwing into the sash-receiving pocket refusesuch as banana-peelings, peanut-shells, and the like.

On the lower sash-rail there is provided a sash-lift 27, composed, preferably, of leather. On the lower sash-rail of the upper sash there is secured in any suitable manner a sash-lift 28, which is also preferably formed of leather. Immediately below this sash-lift there is secured on the upper rail of the lower sash another sash-lift, 29, which is preferably formed of metal, as brass or the like, and which is provided with an outwardly-extending portion 30, which projects beyond the outer edge of the sash-rail in such a position that when the lower sash is lifted it comes into contact with the sash-lift 28, by which its further upward movement is restricted. In order to prevent rattling and keep the top sash firmly seated in its rests, a strong spring 33 is arranged at the top of the window-opening in position to bear against the upper rail of the top sash.

In the normal or closed position of the parts the sashes rest in the positions shown in Figs. 1 and 2. If it is desired to lower both sashes into the sash-receiving pocket, the sash-lift 27 is grasped and the sash is lifted thereby until the rear part of the projection 30 comes in contact with the sash-lift 28. When the sash has reached this position, a knob 32 on the cover 23 is grasped in the hand and the cover is turned inwardly on its hinge. It is obvious that when the lower sash is lifted to a slight extent the rabbeted edge of the cover will be able to clear the lower sash-rail and the sash-lift 27 secured thereto. WVhen the cover 23 has been turned inwardly, the lower sash is drawn forward and dropped into the receiving-pocket. The sash-lift 28 is then grasped, by which means the upper sash may be lifted, (the pin 15 being unseated,) and the sash may then be drawn forward and also lowered into the sash-receiving pocket. It is obvious that the upper sash can be lowered without disturbing in any way the position of the lower sash, since the height of the groove 14 is sufficient to permit the lower sash-rail to clear the upper rail of the lower sash.

For the purpose of permitting the pin 15 to be drawn inward beyond the post 9 after it has passed through the passage-way 17 the post is reduced in width at the inner side, as indicated clearly at 34 in Fig. 6, so that when the molding 10 is secured to the inner face of the post with the edges overlapping equally the edges of said face to form the curtaingroove 13 the edge of the molding on one side is still inside of a line passing through the bottom of the sash-groove 14, whereby the inward movement of the sash is unobstructed when the pin 15 is drawn out of its groove.

When it is desired to remove the lower sash, the sash-lift 27 is grasped and the sash is raised until the beveled portion 18 of the side stile thereof comes into a position opposite to the beveled portion on the partingstrip 18, when the sash may be freely drawn forward. In order to permit this upward movement, the upper sash will first have to be slightly lifted.

It is obvious that it will not be necessary to bevel both the sash-stile and the partingstrip, but that the sash could be made 'removable by beveling only one of these parts.

Obviously the construction hereinbefore described admits of considerable modification without departing from my invention, and I do not wish to be restricted to the specific construction hereinbefore described.

What I claim is-- 1. A window construction comprising a window-frame, a movable window-sash, a sash-groove in the window-frame having a rearwardly and downwardly curved portion terminating in a seat, means on the windowsash engaging said groove and resting in said seat when the sash is in its normal position, and a passage-way leading from said groove but stopping short of the forward edge of the frame, whereby the sash may be freely removed without disturbing the connecting parts.

2.
